One of the most underused vegetables in my opinion is leeks. Lately, it has been becoming more mainstream, but the next time you’re out at the market, be sure to grab a bundle of these amazing green leafy stems. They add so much depth and are perfect to add to your casseroles and soups!

Leeks pair amazingly well with red peppers. Once they are sauteed together and the flavors have infused, it creates a complexity that is to die for! This leek and pepper breakfast strata recipe uses Italian bread that is cut into large bite size chunks, but you’re welcome to use sourdough bread, or choose your favorite whole bread.

What is Strata?

Is strata a breakfast casserole? The name strata may have you questioning if this is indeed an easy breakfast recipe -it is! Strata is a breakfast casserole dish that includes whisked eggs, chopped or sliced bread, and cheese. Then you can add whatever toppings or ingredients you desire to make the strata recipe your own.

What do you add to a breakfast strata?

Outside of the eggs, bread, and cheese, you can be creative with a breakfast strata recipe. For a savory strata recipe, you can use garden flavors such as mushrooms, tomatoes, and spinach. You can make a Mexican breakfast strata recipe with chorizo, peppers, and a Mexican cheese blend. Or you can even go sweet by making it with cream cheese and berries!

How do you cook a breakfast strata?

For this leek and pepper breakfast strata recipe, we are going to bake it -which is the traditional and most commonly used method; but you are welcomed to cook it in a slow cooker too!

Can breakfast strata be frozen?

Yes! Just make a batch and skip the cooking process, and hold off on the shredded cheese (if desired) until it is time to bake. Make sure to double wrap the casserole in heavy duty aluminum foil and freeze up to 3 months. When it is time to bake, remove the frozen breakfast strata and allow it to thaw for at least half an hour before topping with cheese and baking for at least an hour, or until warmed through.

How To Make A Leek Breakfast Strata Recipe

The first step to making your breakfast strata recipe is mixing eggs, spices, and milk in a bowl. Set it to the side.

Next you’re going to saute your leeks and red peppers in a pan. Remember to season the layers, so here you’ll also add a little bit of salt and pepper to taste.

Finally, you will assemble your leek and pepper breakfast strata recipe. Grease a 9×13 casserole dish and add in your chunks of bread, top with your cooked leeks and red peppers, generously sprinkle over your shredded Parmesan and cheddar cheese, then seal it with your egg mixture. Cover your leek and pepper breakfast strata with aluminum foil -loosely. Bake for 40 minutes, remove the foil and allow to cook a few more minutes to give a beautiful golden color on top.

What is a leek?

You may be wondering what is “leek”, what does a leek taste like,  what does a leek look like, do I use the whole leek, and when are leeks in season?

What does a leek look like?

Leeks are firm long green vegetables. The tops of leeks are a dark green that transitions into an almost white color at the bulb. Leeks are usually sold in sets of three at the market.

What does a leek taste like?

Many people use leek in place of onions, since leeks are related to onions. But leeks are milder in taste. Also, to some people, leeks have a slight anise flavor when cooked which is why leeks are the perfect addition to savory dishes -especially soups, like this potato leek soup.

What part of a leek do I use?

For cooking you’ll use the lighter end and bulb of a leek. Cut out the dark green stems and use them if desired in your next batch of homemade vegetable stock.

Once you cut out the dark leafy part of the leek, you’ll cut the leek in half and rinse it thoroughly. Leeks are dirty vegetables so separate the layers to rid the leeks of all of the dirt and debris.

How do you chop a leek?

Once you have discarded the dark green part of the the leek and rinsed the bulb and lighter part clean, it is time to chop the leek. To chop a leek you chop it like you would a cucumber. Since it’s already sliced in half from cleaning, once you chop the leek, it will resemble a half moon. This is what you want.

    We made this last night for dinner with a few additions and changes. We halved the recipe for most of the ingredients since it was just for the two of us. Since we had leftover ham, added about 1 cup, 1 cup chopped broccoli flowerets, 1 chopped jalapeño (we love spice), and we picked wild leeks in the woods so we used about 3/4 cup since they’re small, used roasted garlic and herb seasoning, dill and garlic and herb seasoned Italian bread. We love to experiment with recipes and your recipe was DELICIOUS! We had to bake it at end for another 20 minutes without the foil as we OVERLOADED the casserole and had to use a baking sheet to catch any drippings but there weren’t any. I took a picture of the finished result but didn’t know where to show it. THANKS AGAIN FOR A GREAT RECIPE!!!

    Made this dish last year for family on May long weekend and they were amazed by it. I made a few tweaks to it by adding some bacon and mushrooms as well as wild leeks. Let’s just say they said it was so bomb that I’ve been requested to make each year. Thanks for the recipe!
